No truth was more central to Aum than the principle that world salvation could be achieved only by bringing about the deaths of just about everyone on this earth. Disciples described their embrace of this vision and their understanding of its evolutions from Hindu, Buddhist, and Christian doctrine, but they always assumed that the world-ending violence would be initiated by others, not by the cult itself.

Yet Asahara’s idiosyncratic version of these traditions came to focus on the Buddhust concept of poa, which, in his distorted use, meant killing for the sake of your victims: that is, to provide them with a favorable rebirth. One can speak, then, of a weapon-hungry cult with a doctrine of altruistic murder – murder ostensibly intended to enhance a victim’s immortality. The doctrine sanctified not only violence against the world at large but the killing of numerous individuals who ran afoul of the guru’s aspirations.

Japanese police in December 2010 confirmed that a total of 6,583 people fell victim to the 1995 sarin gas attack on the Tokyo subway system and seven other crimes committed by the Aum Shinrikyo cult.

Earlier this month the death sentence for Masami Tsuchiya, a former senior member Aum Shinrikyo cult who was convicted over a series of crimes committed by group members, became final.

Tsuchiya, 46, is the 11th Aum member to be sentenced to death. He received the death sentence in January 2004 for playing a key role in the murder of 13 people in crimes committed by the sect, including two separate deadly sarin gas attacks, as well as the murder of a young man.
